Intragroup competition in public good games: The role of relative performance incentives and risk attitudes

We analyze a public good game (PGG) with intragroup competition in which, generally but not always, the dominant strategy is to not contribute; therefore, free riding is the unique Nash equilibrium, not achieving Pareto efficiency. We propose a PGG setup where subjects' contributions are rewarded with different individual returns following a rank‐order voluntary contribution mechanism. It is found that the resulting competition for a better return significantly increases contributions. This effect is sensitive to the salience of return differences rewarding higher contributions. Furthermore, the positive effect of return differences on contribution levels depends on an individual's return‐to‐risk sensitivity as elicited through an independent risk elicitation task.     

WORKERS' ENTERPRISES AND THE TASTE FOR PRODUCTION: THE ARTS, SPORT AND OTHER CASES

This paper shows that the standard result according to which labour-managed (LM) firms produce a lower amount of output, as compared with profit-maximizing firms, is reversed if production per se gives utility and the workers' membership of LM firms is set before market decisions. Under the same hypotheses, the LM firms set a higher product quality than the profit-oriented ones, ceteris paribus . The considered hypotheses are appropriate in several sectors, but they are particularly relevant in the case of the performing arts.     

Gender diversity,cash holdings and the role of the institutional environment: empirical evidence in Europe

While substantial evidence is emerging internationally on higher risk aversion among women than among men, there is less evidence on women’s business choices. We explore some of the reasons for the relationship between gender diversity and cash holdings. Specifically, this paper focuses on the choices involving the stock of cash held by firms in which women have executive roles and can consequently exert a crucial influence on the firms themselves. We estimate our proposed empirical models using a dataset of 12,466 observations from 18 European countries. We find a positive relationship between the presence of women with executive roles in the firm and cash holdings. Women tend to make more conservative choices probably because they are more risk averse than men are. This propensity has a relevant impact on the financial choices of firms when women play a leading role. Notably, the study demonstrates that the institutional environment and industry differences moderate our baseline relationship.     

Supply Chain Relationships and SME Firms' Competitiveness in the Spanish Pig-to-Cured Ham Chain

The objective of the article is to examine whether relationship quality in the Spanish pig-to-cured ham supply chain positively influence small and medium enterprise (SME) stakeholders' competitiveness. A structural equation modeling approach has been used with information from a survey conducted on farmers, processors, and retailers in the pig-to-cured ham chain located in the Spanish region of Aragon.

Results indicate that the quality of the relationship positively influences stakeholders' competitiveness in the supply chain. Second, improvements in communication also positively affect the quality of the relationships. Then, the quality of communication has also a positive effect on stakeholders' competitiveness through the relationship quality.     

Investment cash flow sensitivity and financial constraint: a cluster analysis approach

This article sheds light on the mixed empirical evidence concerning financial constraint and investment sensitivity to cash flow. The literature suggests that measuring financial constraint is far from straightforward, and we therefore propose a cluster analysis procedure to identify unambiguous groups of constrained firms. We found the investment results to be highly sensitive to cash flow for financial constraint firms. Moreover, in line with previous research, our results showed that the traditional criteria used to identify financially constrained firms led to ambiguous interpretations. Overall, our results propose that the cluster analysis can be used to encompass the various single-criterion approaches, thereby providing a finer measurement of the financial constraint construct and deeper insight into the relationship between investment sensitivity to cash flow and financial constraint.     

Systemic liquidity contagion in the European interbank market

Systemic liquidity risk, defined by the International Monetary Fund as “the risk of simultaneous liquidity difficulties at multiple financial institutions,” is a key topic in financial stability studies and macroprudential policy-making. In this context, the complex web of interconnections of the interbank market plays the crucial role of allowing funding liquidity shortages to propagate between financial institutions. Here, we introduce a simple yet effective model of the interbank market in which liquidity shortages propagate through an epidemic-like contagion mechanism on the network of interbank loans. The model is defined by using aggregate balance sheet information of European banks, and it exploits country and bank-specific risk features to account for the heterogeneity of financial institutions. Moreover, in order to obtain the European-wide topology of the interbank network, we define a block reconstruction method based on the exchange flows between the various countries. We show that the proposed contagion model is able to estimate systemic liquidity risk across different years and countries. Results suggest that our effective contagion approach can be successfully used as a viable alternative to more realistic but complicated models, which not only require more specific balance sheet variables with high time resolution but also need assumptions on how banks respond to liquidity shocks.

Optimal pricing and investment for resources with alternative uses and capacity limits

Airport runways, radio spectrum, and hospital beds are resources with capacity limits used to provide multiple services with specific capacity requirements in separate markets, which contribute to recover capacity investment costs. A welfare-maximizing and (possibly) budget-constrained firm, whose operating costs significantly increase as total capacity use presses against capacity, chooses prices and capacity. When the equilibrium capacity is reached, second-best Ramsey prices must be adjusted, and mark-ups on marginal costs may be higher for services with higher demand elasticities, if they intensively use capacity. Moreover, for a given output vector, the firm invests more than in first best. Instead, the equilibrium capacity may be first best when there is excess capacity to reduce operating costs and thus improve welfare. Our model can be used as a benchmark to evaluate the efficiency of market mechanisms for resource allocation and pricing, or when market mechanisms are not adopted.
